err-ing first totheembodime'nt ofmy in- 44' ve'nti n selected for. illustration of the separable bottom stop members andthe of a-socalled multiple operated or slide fastening de--' vice associated therewitlnl have shown (Figs.

'1. 3'. and 11;) a' female member I attached to one 50 end of arstringer Iin'the' form of a tape having abead'ed'edgie land a male member 4 attached toi on: edge of a; stringer 5 having a beaded e 8e a I I Thefemale member is'preferably formed from N. sheet metal and in itsinitial state is in theform 1, 2., and 12. In order to clamp thefemale memof a blank like that illustrated in Fig. 8. This blank is folded in any suitable'manner so that I 'it takes the form illustrated in Figs. 9, 10, and 11 and then the lateral projections "I and 8 are clamped together, as ,shown in Figs. 1 and 5. 5

Thereafter the stringer-engaging portifin's 8 of the female member are bent to the shape shown in Figs. 1 and .2. The reason for having-the stringer-engaging portions 8 more curved in the first stages of the forming of the female meml0 ber 'will be apparent from an inspection of Figs. 8 and 9 because their lower ends must be spacedsubstantial distances apart in order to provide suflicient material between them at the lower end of the blank (Fig. 8) to form the loop portion 15 "I which. is adapted to cooperate with the male member 4 in a manner more fully hereinafter described. The female member is also provided with tooth-like'projections H extending from opposed edges of the stringer-engaging portions. 8

to assist in holding the'female'member in posi-' tionon the stringer 2.' Furthermore, the female member is provided with fastener element engaging means herein illustrated as two fastener-engaging members l2--|2; as'shown in Figs'.' 1 8,

and 9.

' The male member 4 is formed from sheet metal and is more or less in the form of a pin substantially U-shaped in cross-section (Fig. 6) and is clamped to the head 8 on the stringer 5.

The inter-engaging parts of the separable end members comprise the loop: portion III of the female member I and the slightly thinned portion I3 of the male member 4, as clearly shown in Figs.

ber securely to the head 3 of the-stringer 2; I have found that the ends of the loop Ill, adjacent to where theyjoin .the stringer-engaging portion 8. 1 should be clamped-together. .Thus the clamping projections 'l and I havebeen provided for that m purpose. Therefore it is necessary to have the loop 18 extend 'below the end of .the'stringer 2. It

is also, therefore,"nec'essary to have the loop-engaging portion. il'extend below the stringer I.

A -neat, durable. and simple attachment "of the female membervi -a'.ndth e'male member 141s provided-"by so forming each stringer that the beadportions will extend along one 'side'edge and then along the lower'edg'e ofeachstringer, as clearly shown in.Figs.-1 and 2. This formation is carried out by taking a stringer, having a head portion jextending .alongone side edge and first cuttinga" .slit in the stringer from the beadless edge to a point adiacent the. beading atthe other edge.

slit entendinmin' my preferred vform, at subit will lie along the beadless edge of the main portion. As a result, the beaded edge of the end portion will lie along the lower end of the stringer providing, when in final position, a bead portion in the form of a continuous member extending along one side edge and then along the lower edge of each stringer, as clearly shown in Figs. 1 and 2. This position of the bead is maintained by overlapping the portion l4 (Fig. 2) with relation to that portion of the stringer above it and then holding the overlapping portions together by cement or any other suitable means. The portion l5 of the stringer 5 is overlapped and secured with respect to the stringer 5 in the same manner.

To the bead of each stringer 2 and 5 I have attached a series of fastening elements 16 which may be of any well known construction. I prefer, however, to use fastening elements each of which has a projection I! on one face and a recess I8 on the other face, as illustrated in Fig. 2. I have also provided a slider l9 which moves relative to the fastening elements-l6 to engage and disengage them in 'the usual manner.

My improved end separable members secured to the stringers 2 and 5 Just beyond the lower ends of the rows of fastening members l6, as

heretofore described, are simple in construction, durable, easy to operate and particularly desirable when the stringers are attached to articles having openings which are to be completely opened at both ends. Assuming that the stringers are-entirely separated, engagement thereof by means of the fastening elements I8 is effected by moving the slider to the lowest position on the stringer 2 where it passes over all but the loop Portion ID of the female end separable member I, as clearly shown in Fig. 4. Then the operator grasps the lower end of the stringer 5 and inserts the male member 4 into the slider (Fig. 4) and moves it downwardly through the slider (with the stringer passing out through the groove between the usual upper and lower portions of the slider not herein shown in detail) until the loop-entering portion i3 enters the loop ID, as shown in Fig. 3; It will be noted that the edges of the female member I and the male member 4 adjacent to the outer edges of the stringers 2 and 5 are so shaped that they will not interfere with eachother during the engaging operation and to this end these edges are so shaped that they diverge slightly from each other from top to bottom of the members, as clearly shown in Figs. 1 and 2. Thus there is a sort of rocking action which takes place between the male member 4 and the female member I during engagement of those members, the final rocking operation taking place when the slider is pulled upwardly after the male member has reached the position shown in Fig. 2. Thus as the parts pass through the slider their lower ends move outwardly to positions shown in Figs. 1 and 2. It will be apparent to anyone skilled in the art that the elongated loop I0 is therefore a necessary feature to .permitproper engagement of the parts. 7

As the slider is moved upwardly from a position shown in Fig. 3, the first two fastening elements ating to hold the end members together and prevent accidental separation of the end fastening members adjacent to their upper ends. It is, of course, understood that the loop l0 and loopengaging portion l3 cooperate to prevent accidental separation of the end separable fasteners at their lower end. Furthermore, it is clear that the slider can be moved upwardly only when the end members are engaged as shown in Fig. 3.

One trouble encountered with fastening means of the type illustrated and described has been in connection with the fastening members i6 becoming accidentally disengaged below the slider thereby preventing downward movement of the slider beyond the point where the fasteners are disengaged. In order.to make it'easy to place the parts in proper operating positions after such an accident I have provided a simple and efficient stop member 20, herein illustrated as being secured to the stringer 2 Just beyond the upper end of the series of fastening elements l6 secured to that stringer. This stop member is provided with opposed stringer-engaging portions 2l -'2l secured to opposite sides of the stringer 2 as by rivets 22 and are connected adjacent to the head 6 by a relatively narrow beaded portion 23 for purposes hereinafter described. This stop member 20 has a pair of oppositely projecting ears 2424 which prevent the slider from being moved entirely past the stop member; Opposite this stop member 20 on the other stringer 5 there is provided fastening elements l6 which are to act as means to prevent that stringer from pulling through the slider when in its uppermost position. I have attached to the stringer 5 beyond the series of fastening elements IS a clamping piece 25 which acts mostly as a protector against 1 displacement of the last fastening element I6 on that stringer. a

When the slider is moved to a position where it engages the ears 24-24 of the stop member 20 (Fig. 2) the stringers may besepar'ated after becoming accidentally disengaged by merely grasping them and pulling them apart laterally to unfasten the fastener member l6. As the last two fastener members are disengaged just below the. slider, then the remaining fastening members (herein shown as two in number) on the stringer 5 may be moved out of the bottom of the slider because the width of the bead 23 of the stop member 20 is sufficiently narrow to permit passage of the fastening element l6 and the clamping piece 26 between the outer edge of the bead and the wall of the slider, as clearly illustrated in Fig. 2. After the stringer 5 has been pulled entirely free from the slider l9 then the slider may be moved to the bottom of the stringer 2 and the end separable fastening element may be engaged and the slider moved upwardly again properly to engage the fastening members l6.

Referring now to Fig. 13, I have shown .end fastening members of the same construction and operation as those described in connection with Figs. 1, 3, and 4, except that the fastener-engaging members l2-l2 are on the male member instead of the female member. This is to show that the members may be made either way to secure the desired results.
